Medicare fight hits House, Senate races

The battle over Social Security and Medicare has been resurrected in House and Senate races across the country, with candidates and their allies stretching the truth as they squabble with opponents about who would inflict the most damage on the nation's seniors. For both parties, the messaging in congressional races echoes that in the presidential race, where Republicans are hammering President Obama over the healthcare reform law he pushed through Congress, and Democrats are blasting Mitt Romney over his support for the budget proposal drafted by Rep. Paul Ryan (R-Wis.), which restructures Medicare.
